Genes affected

CHST15 (HGNC:18137): (carbohydrate sulfotransferase 15) Chondroitin sulfate (CS) is a glycosaminoglycan which is an important structural component of the extracellular matrix and which links to proteins to form proteoglycans. Chondroitin sulfate E (CS-E) is an isomer of chondroitin sulfate in which the C-4 and C-6 hydroxyl groups are sulfated. This gene encodes a type II transmembrane glycoprotein that acts as a sulfotransferase to transfer sulfate to the C-6 hydroxal group of chondroitin sulfate. This gene has also been identified as being co-expressed with RAG1 in B-cells and as potentially acting as a B-cell surface signaling receptor. Alternative splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Jul 2012]

Ambry Genetics

Jun 16, 2024

The c.1069G>T (p.A357S) alteration is located in exon 5 (coding exon 4) of the CHST15 gene. This alteration results from a G to T substitution at nucleotide position 1069, causing the alanine (A) at amino acid position 357 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
